IMPROVEMENT IN REVOLVING FIRE-ARMS.

Specification forming part of Letters Patent No. 191, 78, dated May 22, 1877 application tiled December 29, 1976.

To all whom. it may conceiz:

. Be it known that I, CHARLES' H. RICHARD SON, of Philadelphia, Pennsylvania, have invented a new and useful Improvement in Revolving Fire-Arms, of which the following is,

a specication:

The object ot' my invention is to construct a revolving tire-arm of greater capacity than .A tion on the line 1 2.

rPhe frame A of the fire-arm is constructed substantially as usual 5 but its barrel Bis elongated vertically, and has two bores, a and b, I

one above the other.

The lower bore a is in line with the cartridge chambers of the usual cylinder D, while the bore b is in line with cartrid ge-chambers formed in a ring, E, which embraces the cylinder D, but is at liberty to turn freely thereon.

The firearm has two hammers, F and G, and two triggers, I andJ, the hammer F and trigger I acting in .conjunction with the cylinder D, and entirely independent of the hammer G and trigger J, which act in conjunction with the ring E.

The hammer F is hung upon a sleeve. d, which is attached to the hammer G, and turns upon the usual pivot-pin. l

The hammer F carries the usual operatinginger e, which acts upon a ratchet on the rear of the cylinder D, and serves to partly .t turn the same when the hammer is raised, the

locking ot' the cylinder during the firing operation being eii'ected by means of a bell-crank lever, f, hung to a pin, i, the end of one arm -of thisV bell f crank lever being adapted to notches cut in the rear of the cylinder D, while the end of its other arm is acted upon by a cam, m, on the side of the hammer F.

This cam mis of a peculiar character, as

best observed in the perspective view, Fig. 4, on reference to which it will be seen that the cam at its commencement is comparatively thick, but gradually decreases in thickness from front to rear, so that as the hammer is raised the cam will only act on the lever f, so as to withdraw the end of the same from the slot in the cylinder, and-allow the latter to move slightly when the narrow portion ot' the cam will permit the outer end ot' the lever to move upward, so that its front end will bear upon the rear edge of the cylinder, so as Vto project into the next notch in the same as it is turned. l Y

Upon the descent of the hammer the outer yend of the lever is moved sidewise until it is brought in line with the front end of the cam, which is so close to the pivot-pin that the end of the lever is allowed to spring in close to the hammer, so as to be in position for being again acted on by the cam upon raising the hammer.

The turning of the ring.E is effected by means of a linger, n, hung to an arm. p, carried by the end of the sleeve d, this ringer acting on notches s, formed in the rear edge ot' the ring, the locking of which is'eft'ected by means of a bell-crank lever, P, hung to the 1n t, p One arm of this lever has an end' adapted to recesses in the periphery of the ring E, while the other is adapted to a cam, x, on the edge of the hammer G, this cam being of such a character that it will operate the lever P, so as to lock and release the ring E, in the same manner as the lever f is caused, by the cam m on the hammer F, to lock and release v the cylinder D.

It will be evident that by my invention the capacity of a fire-arm can be increased largely without vunduly increasing its size or weight.

I claim as my invent-ionl. The combination, in a revolving firearm, of the following elements, namely: a barrel, B, with two bores, a revolving chambered cylinder, D, a revolving cham bered ring, E, and two independently-operating hammers, F and G, as set forth.

2. The combination of the cylinder D, proname to this specification in the presence of vided with ratchet and recesses, with the bell two subscribing Witnesses. crank lever f, and the hammer F, having' a,

finger, e, and the eem m on one side, cou- GHARLES H RICHARDSON struoted and operating substantially as set Witnesses: forth. HERMANN MoEssNER,

In testimony whereof I have signed my HARRY SMITH.
